Message-Id: <1427987231-3669-12-git-send-email-nicolas.dichtel@6wind.com> Date: Thu, 2 Apr 2015 17:07:10 +0200 From: Nicolas Dichtel <nicolas.dichtel@...nd.com> To: netdev@...r.kernel.org Cc: davem@...emloft.net, eric.dumazet@...il.com, Nicolas Dichtel <nicolas.dichtel@...nd.com> Subject: [PATCH net-next v2 11/12] dev: set iflink to 0 for virtual interfaces Virtual interfaces are supposed to set an iflink value != of their ifindex. It was not the case for some of them, like vxlan, bond or bridge. Let's set iflink to 0 when dev->rtnl_link_ops is set.
